It appears that LVMH is stomping on all the decant sites and stopping them from selling Guerlain, so look for more bargains in that space.
STC is offering Jicky at a mere $30 for 1 ml at that sale price. Add in shipping, and I'm afraid I can't kid myself that that's a bargain. I paid $40 for a two-thirds full bottle of 100 year old Jicky, in box.
Any more details on how they'd stop it? After all anybody can buy a bottle of Guerlain, decant then sell it - if not in the US then somewhere more pliable.
It would be interesting if they extended that to the grey market. It's where you dump the product after you failed to guess the right quantity for the launch. It allows you plausible deniability: no, you're not selling your $400 bottles for $40, it's these scum grey market sites who swooped to buy the stock "unethically" (but then who sold it to them in the first place?). Nevertheless you don't take (as much of) a loss on the 400,000 units you accidentally overproduced (today, perfumes are produced in a single run and never again). This is relatively important as the brands are not themselves holding the IP for their own perfumes, rather IFF/Givaudan/etc. is and selling them the juice at a fairly consequent markup from production cost. I always thought this dynamic prevented the brands from going hard on grey market sites and the discount retailers in the seedier parts of town.
As for $40 for an old bottle, you got a bargain, but most people won't. Samples are always expensive compared to the manufacturer - even AbdesSalaam samples are about the same on STC/TPC for 2ml as they are for 5.5ml on profumo.it. I personally see value in being able to try something, now the advantage is that there's a great perfume lovers group in my area so I can now just ask members if they have the FB of the stuff, but if you live somewhere with less options it might well be worth it. Could you really buy another bottle of 100 year old Jicky for $40?
